I have big problem with mysql+memcached, if mysql crash for few seconds, php/apache continue to work and because I have bad php cms it simple caching bad things because can`t get data from mysql and when mysql again start to work (auto restart with chkserv) I have blank homepage because I have bad cache in memcached! Now I want to auto reload memcached after mysql restart, is it possible? in /etc/chkserv.d for mysql I have this: service[mysql]=x,x,x,/usr/local/cpanel/scripts/restartsrv_mysql;/etc/init.d/memcached reload,mysql,mysql but this simple don`t working, mysql start to work but memcached not reloaded after it, look like second command "/etc/init.d/memcached reload" not executed because mysql start to work after first command!? Is this true or I have some other problem? How to reload memcached after mysql start/re-start? Thanks.

  Instead of "reload" try restart: /etc/init.d/memcached restart
  Mysql is extremely stable usually, so you should try to figure out why its crashing. Check you logs.

  reload command working fine but look like chkserv simple stop with first command (mysql restart) if mysql start to work... I need this because mysql sometimes crashing because on backup TOTAL RAM usage go up from <20GB to over 30GB and mysql process virutal mem usage go up to 25GB+ from ~10GB, I still checking why, in my.cnf I have set total maximum memory usage ~20GB, result from tuning-primer.sh: MEMORY USAGE Max Memory Ever Allocated : 9.87 G Configured Max Per-thread Buffers : 10.35 G Configured Max Global Buffers : 9.51 G Configured Max Memory Limit : 19.86 G Physical Memory : 31.32 G

  I recommend resolving the issue that is causing MySQL to fail that often. You may want to post on our Optimization forums for assistance with troubleshooting the MySQL failures. Thank you.

  Yes, I need to fix it but also I need option to execute multiple commands per service in chkserv.d, is that possible? On every mysql restart/start I need to reload memcached, is that possible? Thanks.

  You could try using the "&" symbol rather than a comma when adding the additional command. EX: /usr/local/cpanel/scripts/restartsrv_mysql & /etc/init.d/memcached reload
  Or, you could manually edit "/usr/local/cpanel/scripts/restartsrv_mysql" to reload memcached. Thank you.
